Fig. 3From: Overexpression of Klotho suppresses liver cancer progression and induces cell apoptosis by negatively regulating wnt/β-catenin signaling pathwayKlotho expression suppresses liver cancer cell growth by colony formation assay. a The liver cancer cell line of HepG2 and SMMC-7721 was used for colony formation assay. b Histogram of clone formation ratio was shown in pCMV6-Klotho group, control plasmid group, or untreated group. **p < 0.01, compared with the cells transfected with pCMV6-vectorBack to article page
